BlackBerry Device with QWERTY Keyboard and Trackball Design
This 2012 patent describes a handheld device, like an early BlackBerry, with a QWERTY keyboard and a trackball, focusing on the physical arrangement of keys around the navigation tool.
Original patent title: “Handheld wireless communication device”
This 2012 patent describes a handheld device, like an early BlackBerry, with a QWERTY keyboard and a trackball, focusing on the physical arrangement of keys around the navigation tool. Granted to Research in Motion Ltd in 2012 with 25 claims, and it is expected to expire in 2027.
Coverage
What does this patent actually cover?
This patent covers a handheld device designed to be held and used with one hand for typing text messages. It features a display, a keyboard with keys arranged in columns that are offset from each other, and a trackball for navigation. Specifically, it details how at least one key is shaped to fit snugly against the curved edge of the trackball, creating a seamless interface. The device uses a microprocessor to process commands from the keys and trackball to change what's shown on the display. The keyboard layout is a traditional QWERTY, with the top row starting with Q, W, E, R, T.
The gap
What does this patent NOT cover?
- Devices that do not have a physical keyboard with alphanumeric keys.
- Devices where the keys are not arranged in vertically offset columns.
- Devices that do not include a trackball navigation tool.
- Keyboards that do not use a QWERTY layout where the top row starts with Q, W, E, R, T.
- Devices where keys are not shaped to conform to the boundary of the trackball.
These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.
Key facts
What made this novel
The innovation lies in the precise physical integration of the keys with the trackball. By shaping the edge of at least one key to match the curve around the trackball, the design minimizes wasted space and creates a more ergonomic and visually cohesive input area.

While BlackBerry's market share has declined, the principles of ergonomic physical keyboard design and integrated navigation tools are still relevant in niche markets and retro-inspired devices.
Market impact
This patent reflects a specific era of smartphone design where physical keyboards and tactile navigation were paramount. It helped solidify the BlackBerry's distinctive form factor, contributing to its dominance in the business and enterprise mobile market before the rise of large touchscreen devices. The specific physical layout described was a key differentiator for the brand.
